Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.

Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.

Learners read how quality can be built into a manufacturing process.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

Learners examine the internal components of an optical encoder used in automated manufacturing applications. A brief quiz completes the animated activity.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
